ZDNet are reporting that Microsoft have finally decided what terminology to use for their Metro/Windows 8-style UI, where it will simply be referred to as "Windows 8", according to their sources. ZDNet's sources have said that:

Anything currently/formerly known as a "Metro-Style application" (with or without a hyphen) will now be known officially as a "Windows 8 application." References to the "Metro user interface" will now be replaced by "Windows 8 user interface." And instead of saying "Metro design," the Softies and those adhering to their official guidelines will be using the words "Windows 8 design."

Microsoft have been having quite the identity crisis on what they want to name their new UI, where it sat on Metro for quite sometime, but due to a trademark dispute, they changed it to "Windows 8-style UI". This news would make sense, and they've now changed it to something much more simple, "Windows 8". I don't see what all the fuss is over, personally. It's a UI, it's part of Windows 8, why even give it a name and have this much air time about it? Free publicity, maybe?
